A weldment is the joining of two different metal pieces into one weldment assembly. In other words, a weldment is what is produced when different pieces of metal are welded together together. The design for a finished product is called a weldment profile. A weldment design determines what kind of weldment assembly is produced. It should be designed taking into account what function the metal is needed to perform when it is welded together.
There are several different types of welding, and there are multiple types of weldments. Arc welding uses an electric arc to fuse a base or parent metal with the added metal. The current used can be direct or can be an alternating current.
Electrosag welding is used primarily for large horizontal weldments where two large plates need to be welded together. This type of welding might be used in large machine manufacturing. Electrosag welding deposits the additional or weld metal into the space between the two pieces of metal that need to be joined.
Gas metal arc welding, also known as metal inert gas (MIG) welding, is a type of welding that uses a gas to protect the area being welded. The process reduces oxidation and makes it possible to weld very thin sheets of metal together. It is also relatively easy to automate MIG weldments, so this type of welding might be found where robotic methods are used.
